Ships at sea are spoofing their location to evade sanctions, etc.

artmancc writes: Like aircraft, many of the world's ocean-going vessels are required to have transponders that broadcast their location. The information is public and can be seen on websites such as AIS Marine Traffic. But according to an analysis reported in The New York Times , a maritime data company called Windward "has uncovered more than 500 cases of ships manipulating their satellite navigation systems to hide their locations." The article, by Anatoly Kurmanaev, highlights the Cyprus-registered tanker Reliant, which was observed taking on oil at a Venezuelan refinery last December. At the same time, however, the ship was reporting its position as some 300 nautical miles (about 500 kilometers) away, "drifting innocuously off the coast of St. Lucia."
